About

who we are

Stan is freedom-respecting, open-source software (new BSD core, some interfaces GPLv3) for facilitating statistical inference at the frontiers of applied statistics.

The Stan Development Team

The project is a team effort comprised of full time and volunteer developers from around the world.

Stan Governing Body (SGB)

We have a provisional Stan Governing Body that will operate until 23 August 2019.

The scope of the SGB’s authority is all things Stan. That includes ownership/management of trademarks, online resources like Discourse and GitHub and membership in the Stan community. The SGB has authority over:

  • ownership and management of trademarks
  • online resources including the Stan Discourse, the stan-dev GitHub organization
  • membership in the Stan community
  • NumFOCUS funds
  • fundraising in support of Stan
  • defining the scope of the Stan project
  • authorizing and/or running Stan conferences
  • licensing requirements for contributed code and documentation

The SGB is intended to be a transparent body in service of the Stan community and electorate. The SGB will define an electorate and the governance of joining and participating in an electorate. The SGB is expected to use referendums when appropriate to ensure it’s legitimacy. The SGB will publicly post minutes on a regular basis on the Stan Discourse in the general category.

The SGB is to advance diversity in under-represented communities in the Stan ecosystem. The SGB will actively develop and implement strategies to improve inclusion and diversity at all levels of the Stan project and will prepare an annual diversity report.

The composition of the non-provisional SGB will be established through half-board elections every year. Any changes to the electorate will be approved by majority vote of the existing electorate.

To reach the current SGB with any questions, concerns, or feedback, please email board@mc-stan.org.

The current SGB is:

  • Breck Baldwin (Columbia University) [Presiding officer]
  • Julie Bertrand (INSERM)
  • Michael Betancourt (Independent consultant)
  • Jonah Gabry (Columbia University)
  • Andrew Gelman (Columbia University) [Chair]
  • Daniel Lee (Generable) [Secretary]
  • Daniel Simpson (University of Toronto)
  • Sean Talts (Columbia University)
  • Lizzie Wolkovich (University of British Columbia)

Funding

Stan would not exist or continue to exist without the generous support of grants, foundations, and sponsors.

If you are interested in supporting the development of Stan then please see our support page detailing the ways in which you can contribute.

NumFOCUS

Stan is now linked to NumFOCUS, a U.S. 501(c)(3) nonprofit organization that serves several other open-source software projects, including NumPy, Julia, Jupyter, and others.

All financial decisions related to NumFOCUS are made by the Stan Governing Body.

The mission of NumFOCUS is to promote sustainable high-level programming languages, open code development, and reproducible scientific research. We accomplish this mission through our educational programs and events as well as through fiscal sponsorship of open source data science projects. We aim to increase collaboration and communication within the scientific computing community.
